## Why delete_auth_user is rated Critical

User deletion is a destructive operation that cannot be undone without restore from backup. Even though the description is empty, the tool name unambiguously indicates irreversible data removal. This ranks as Destructive rather than Write due to the permanent nature of account deletion.

From the tool's own definition: "Tool name is 'delete_auth_user' with no description provided. The name explicitly indicates deletion of authentication user records, which is irreversible."

## Use case

AI agents call delete_auth_user to permanently remove resources in Supabase MCP Server - Self-Hosted Edition, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
